Hybrid Tea Rose plant named Hilred

ABSTRACT

A rose seedling intended for greenhouse culture and production of cut flowers, the new plant being of the tea rose class and particularly distinguished by its continuous production of medium high centered blossoms, its upright growth with little branching with medium diameter canes topped by long pointed bud of excellent red flower color.

BACKGROUND OF THE NEW PLANT

This new variety of rose plant is a result of my crossing "Jacqueline"(U.S. Plant Pat. No. 2,183) with an undisseminated seedling #4-68R inthe fall of 1979 at Richmond, Ind., with the object of producing aHybrid Tea Rose. The varietal denomination of this new claimed cultivaris `Hildred`. The claimed plant is also known as 2-80R.

The claimed plant was asexually reproduced through successivegenerations by grafting in Richmond, Ind., and at Livermore, Calif.,showing that the distinctive characteristics of the claimed cultivarhold true and appear to be firmly fixed. This new variety can also beasexually propagated by budding, grafting, propagation from cuttings andmicropropagation.

This new rose plant cultivar is a superior plant when it is judged onits long pointed bud form and its clear, bright red color makes it animprovement over seed parent "Jacqueline" (U.S. Plant Pat. No. 2,183).It is better than its pollen parent in productivity and keepingqualities. The claimed plant most closely resembles Hybrid Tea Roseplant named Buram (U.S. Plant Pat. No. 7,052) (hereinafter "Buram") andRose plant Arotrusim (U.S. Plant Pat. No. 7,157) (hereinafter"Arotrusim"). The average size of the flowers of Buram and Arotrusim arelarger than that of the claimed plant. Both the claimed rose andArotrusim bloom continuously in a greenhouse where Buram blooms onlyrecurrently. Furthermore, the bud of the claimed rose is short andpointed without a conspicuous neck whereas the bud of Buram is ovoid andhigh centered and the bud of Arotrusim is long and pointed. The color ofthe foliage of the claimed plant is green whereas in Buram the oldfoliage is purplish green and the new foliage is yellow green. The oldfoliage of Arotrusim is reddish brown and the new foliage is matt green.Both Buram and Arotrusim are disease resistant and have some winterhardiness. The claimed cultivar is not disease or frost resistant.

I claim:
 1. A new and distinct Hybrid Tea Rose cultivar, substantiallyas herein shown and described, characterized by its long pointed buds,the clear bright red color of the flower petals, and by its moderatelyfree and continuous flower production under greenhouse culture.
